net: hns3: fix VF wrong speed and duplex issue If PF is down, firmware will returns 10 Mbit/s rate and half-duplex mode when PF queries the port information from firmware. After imp reset command is executed, PF status changes to down, and PF will query link status and updates port information from firmware in a periodic scheduled task. However, there is a low probability that port information is updated when PF is down, and then PF link status changes to up. In this case, PF synchronizes incorrect rate and duplex mode to VF. This patch fixes it by updating port information before PF synchronizes the rate and duplex to the VF when PF changes to up.

net: hns3: fix port base vlan add fail when concurrent with reset Currently, Port base vlan is initiated by PF and configured to its VFs, by using command "ip link set <pf name> vf <vf id> vlan <vlan id>". When a global reset was triggered, the hardware vlan table and the soft recorded vlan information will be cleared by PF, and restored them until VFs were ready. There is a short time window between the table had been cleared and before table restored. If configured a new port base vlan tag at this moment, driver will check the soft recorded vlan information, and find there hasn't the old tag in it, which causing a warning print. Due to the port base vlan is managed by PF, so the VFs's port base vlan restoring should be handled by PF when PF was ready. This patch fixes it.

If the address of vport A is changed to MAC address B, the driver needs to delete the MAC address A of vport A. Due to the MAC address A of vport A has become invalid in the hardware entry, so "-ENOENT" is returned. In this case, the "used_umv_size" value recorded in driver is not updated. As a result, the MAC entry status of the software is inconsistent with that of the hardware. Therefore, the driver updates the umv size even if the MAC entry cannot be found.

net: hns3: fix ROCE base interrupt vector initialization bug Currently, NIC init ROCE interrupt vector with MSIX interrupt. But ROCE use pci_irq_vector() to get interrupt vector, which adds the relative interrupt vector again and gets wrong interrupt vector. So fixes it by assign relative interrupt vector to ROCE instead of MSIX interrupt vector and delete the unused struct member base_msi_vector declaration of hclgevf_dev.

net: hns3: fix failed to add reuse multicast mac addr to hardware when mc mac table is full Currently, when driver is failed to add a new multicast mac address to hardware due to the multicast mac table is full, it will directly return. In this case, if the multicast mac list has some reuse addresses after the new address, those reuse addresses will never be added to hardware. To fix this problem, if function hclge_add_mc_addr_common() returns -ENOSPC, hclge_sync_vport_mac_list() should judge whether continue or stop to add next address. As function hclge_sync_vport_mac_list() needs parameter mac_type to know whether is uc or mc, refine this function to add parameter mac_type and remove parameter sync. So does function hclge_unsync_vport_mac_list(). Fixes: ee4bcd3b7ae4 ("net: hns3: refactor the MAC address configure") Signed-off-by: Guangbin Huang <huangguangbin2@huawei.com> Signed-off-by: David S.

net: hns3: add support pause/pfc durations for mac statistics The mac statistics add pause/pfc durations in device version V3, we can get total active cycle of pause/pfc from these durations. As driver gets register number from firmware to calculate desc number to query mac statistics, it needs to set mac statistics extended enable bit in firmware command 0x701A to tell firmware that driver supports extended mac statistics, otherwise firmware only returns register number of version V1. As pause/pfc durations are not supported by hardware of old version, they should not been shown in command "ethtool -S ethX" in this case, so add checking max register number of each mac statistic in their version. If the max register number of one mac statistic is greater than register number got from firmware, it means hardware does not support this mac statistic, so ignore this statistic when get string and data of mac statistic.

net: hns3: modify mac statistics update process for compatibility After querying mac statistics from firmware, driver copies data from descriptors to struct mac_stats of hdev, and the number of copied data is just according to the register number queried from firmware. There is a problem that if the register number queried from firmware is larger than data number of struct mac_stats, it will cause a copy overflow. So if the firmware adds more mac statistics in later version, it is not compatible with driver of old version. To fix this problem, the number of copied data needs to be used the minimum value between the register number queried from firmware and data number of struct mac_stats. The first descriptor has three data and there is one reserved, to optimize the copy process, add this reserverd data to struct mac_stats.

ethernet: constify references to netdev->dev_addr in drivers This big patch sprinkles const on local variables and function arguments which may refer to netdev->dev_addr. Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers. Some of the changes here are not strictly required - const is sometimes cast off but pointer is not used for writing. It seems like it's still better to add the const in case the code changes later or relevant -W flags get enabled for the build. No functional changes.

net: hns3: PF support get unicast MAC address space assigned by firmware Currently, there are two ways for PF to set the unicast MAC address space size: specified by config parameters in firmware or set to default value. That's mean if the config parameters in firmware is zero, driver will divide the whole unicast MAC address space equally to 8 PFs. However, in this case, the unicast MAC address space will be wasted a lot when the hardware actually has less then 8 PFs. And in the other hand, if one PF has much more VFs than other PFs, then each function of this PF will has much less address space than other PFs. In order to ameliorate the above two situations, introduce the third way of unicast MAC address space assignment: firmware divides the whole unicast MAC address space equally to functions of all PFs, and calculates the space size of each PF according to its function number. PF queries the space size by the querying device specification command when in initialization process. The third way assignment is lower priority than specified by config parameters, only if the config parameters is zero can be used, and if firmware does not support the third way assignment, then driver still divides the whole unicast MAC address space equally to 8 PFs.

After step 4, the "ethtool -a ethx" command shows both rx and tx pause parameters are on. However, pause parameters of hardware are still off and port has no flow control function actually. To fix this problem, if autoneg is disabled, driver uses its saved parameters to restore pause of hardware. If the speed is not changed in this case, there is no link state changed for phy, it will cause the pause parameter is not taken effect, so we need to force phy to go down and up.

When the system enters the resume mode, the driver needs to implement the resume callback function of the NIC device and restore the device to the state before suspension. When the system enters the suspend and resume mode, the NIC driver actually executes the PF function reset process. When the PFs are suspending/resuming, VFs also enter the suspend/resume state because the PFs trigger the VFs to reset, therefore no operation is required when the VF pci_driver is suspending or resuming.

Each layer can have one offset, and can't be masked when configure flow director rule by ethtool command. The layer is selected based on the flow-type, ether for L2, ip4/ipv6 for L3, and tcp4/tcp6/udp4/udp6 for L4. For example, tcp4/tcp6/udp4/udp6 rules share the same user-def offset, but each rule can have its own user-def value. For the user-def field of ethtool -N/U command is 64 bits long. The bit 0~15 is used for user-def value, and bit 32~47 for user-def offset in HNS3 driver.

net: hns3: refactor flow director configuration Currently, the flow director rule of aRFS is configured in the IO path. It's time-consuming. So move out the configuration, and configure it asynchronously. And keep ethtool and tc flower rule using synchronous way, otherwise the application maybe unable to know the rule is installed or pending. Add a state member for each flow director rule to indicate the rule state. There are 4 states: TO_ADD: the rule is waiting to add to hardware TO_DEL: the rule is waiting to remove from hardware DELETED: the rule has been removed from hardware. It's a middle state, used to remove the rule node in the fd_rule_list. ACTIVE: the rule is already added in hardware For asynchronous way, when receive a new request to add or delete flow director rule by aRFS, update the rule list, then request to schedule the service task to finish the configuration. For synchronous way, when receive a new request to add or delete flow director rule by ethtool or tc flower, configure hardware directly, then update the rule list if success.

Both the PF and VF share the same max rss size, and no more than 128. For DEVICE_VERSION_V3, the max rss size for PF can be up to 512, so there is a new field in configuration file to store it, the old filed is used for VF. To be compatible with boards using old configure file, the PF will use the old filed if the one is zero.

net: hns3: refine the VLAN tag handle for port based VLAN For DEVICE_VERSION_V2, the hardware only supports max two layer VLAN tags, including port based tag inserted by hardware, tag in tx buffer descriptor(get from skb->tci) and tag in packet. For transmit packet: If port based VLAN disabled, and vf driver gets a VLAN tag from skb, the VLAN tag must be filled to the Outer_VLAN_TAG field (tag near to DMAC) of tx buffer descriptor, otherwise it may be inserted after the tag in packet. If port based VLAN enabled, and vf driver gets a VLAN tag from skb, the VLAN tag must be filled to the VLAN_TAG field (tag far to DMAC) of tx buffer descriptor, otherwise it may be conflicted with port based VLAN, and raise a hardware error. For receive packet: The hardware will strip the VLAN tags and fill them in the rx buffer descriptor, no matter port based VLAN enable or not. Because port based VLAN tag is useless for stack, so vf driver needs to discard the port based VLAN tag get from rx buffer descriptor when port based VLAN enabled. So vf must know about the port based VLAN state. For DEVICE_VERSION_V3, the hardware provides some new configuration to improve it. For transmit packet: When enable tag shift mode, hardware will handle the VLAN tag in outer_VLAN_TAG field as VLAN_TAG, so it won't conflict with port based VLAN. And hardware also make sure the tag before the tag in packet. So vf driver doesn't need to specify the tag position according to the port based VLAN state anymore. For receive packet: When enable discard mode, hardware will strip and discard the port based VLAN tag, so vf driver doesn't need to identify it from rx buffer descriptor. So modify the port based VLAN configuration, simplify the process for vf handling the VLAN tag.

To utilize these new resources, extend the corresponding field or variable to 16bit type, and remove the restriction of NIC client that only use a maximum of 65 interrupt vectors. In addition, the I/O address of the extended interrupt resources are different, so an extra handler is needed. Currently, the total number of interrupts is the sum of RoCE's number and RoCE's offset (RoCE is in front of NIC), since the number of both NIC and RoCE are same. For readability, rewrite the corresponding field of the command, rename the RoCE's offset field as the number of NIC interrupts, then the total number of interrupts is sum of the number of RoCE and NIC, and replace vport->back with hdev in hclge_init_roce_base_info() for simplifying the code.

net: hns3: optimize the filter table entries handling when resetting Currently, the PF driver removes all (including its VFs') MAC/VLAN flow director table entries when resetting, and restores them after reset completed. In fact, the hardware will clear all table entries only in IMP reset and global reset. So driver only needs to restore the table entries in these cases, and needs do nothing when PF reset, FLR or other function level reset. This patch optimizes it by removing unnecessary table entries clear and restoring handling in the reset flow, and doing the restoring after reset completed.

net: hns3: use mutex vport_lock instead of mutex umv_lock Currently, the driver use mutex umv_lock to protect the variable vport->share_umv_size. And there is already a mutex vport_lock being defined in the driver, which is designed to protect the resource of vport. So we can use vport_lock instead of umv_lock. Furthermore, there is a time window for protect share_umv_size between checking UMV space and doing MAC configuration in the lin function hclge_add_uc_addr_common(). It should be extended. This patch uses mutex vport_lock intead of spin lock umv_lock to protect share_umv_size, and adjusts the mutex's range.

net: hns3: refactor the MAC address configure Currently, the HNS3 driver sync and unsync MAC address in function hns3_set_rx_mode(). For PF, it adds and deletes MAC address directly in the path of dev_set_rx_mode(). If failed, it won't retry until next calling of hns3_set_rx_mode(). On the other hand, if request add and remove a same address many times at a short interval, each request must be done one by one, can't be merged. For VF, it sends mailbox messages to PF to request adding or deleting MAC address in the path of function hns3_set_rx_mode(), no matter the address is configured success. This patch refines it by recording the MAC address in function hns3_set_rx_mode(), and updating MAC address in the service task. If failed, it will retry by the next calling of periodical service task. It also uses some state to mark the state of each MAC address in the MAC list, which can help merge configure request for a same address. With these changes, when global reset or IMP reset occurs, we can restore the MAC table with the MAC list.

net: hns3: refactor the precedure of PF FLR Currently, the actual work of PF FLR is handled in the reset task, which is asynchronous. So in some case, if the preparing and rebuilding are not done, then the PF FLR will trigger some problems, for example, makes hardware go into chaos. So this patch separates the process of PF FLR from reset task, and adds a semaphore to serialize this reset and others. When FLR's preparing fails, if there has other higher level reset pending or failing times less than the HCLGE_FLR_RETRY_CNT, this preparing should be retried, otherwise PF and its VF may get into wrong state. BTW, while the hardware reports misc interrupt during pcie_flr(), the driver can not receive this interrupt anymore, so disable it when hclge_flr_prepare() return, and re-enable it when enter hclge_flr_done().

BTW, since hclge_clear_reset_cause() and hclge_reset_prepare_up() will not affect the device, so in hclge_reset_rebuild(), these functions are called without rtnl_lock.

net: hns3: not allow SSU loopback while execute ethtool -t dev The current loopback mode is to add 0x1F to the SMAC address as the DMAC address and enable the promiscuous mode. However, if the VF address is the same as the DMAC address, the loopback test fails. Loopback can be enabled in three places: SSU, MAC, and serdes. By default, SSU loopback is enabled, so if the SMAC and the DMAC are the same, the packets are looped back in the SSU. If SSU loopback is disabled, packets can reach MAC even if SMAC is the same as DMAC. Therefore, this patch disables the SSU loopback before the loopback test. In this way, the SMAC and DMAC can be the same, and the promiscuous mode does not need to be enabled. And this is not valid in version 0x20. This patch also uses a macro to replace 0x1F.

net: hns3: clear reset interrupt status in hclge_irq_handle() Currently, the reset interrupt is cleared in the reset task, which is too late. Since, when the hardware finish the previous reset, it can begin to do a new global/IMP reset, if this new coming reset type is same as the previous one, the driver will clear them together, then driver can not get that there is another reset, but the hardware still wait for the driver to deal with the second one. So this patch clears PF's reset interrupt status in the hclge_irq_handle(), the hardware waits for handshaking from driver before doing reset, so the driver and hardware deal with reset one by one. BTW, when VF doing global/IMP reset, it reads PF's reset interrupt register to get that whether PF driver's re-initialization is done, since VF's re-initialization should be done after PF's. So we add a new command and a register bit to do that. When VF receive reset interrupt, it sets up this bit, and PF finishes re-initialization send command to clear this bit, then VF do re-initialization.

So this patch delays clearing handshake status just before UP, and recovers this status when reset fail. BTW, this patch adds a new function hclge(vf)_reset_handshake() to deal with the reset handshake issue, and renames HCLGE(VF)_NIC_CMQ_ENABLE to HCLGE(VF)_NIC_SW_RST_RDY which represents this register bit more accurately.

net: hns3: process H/W errors occurred before HNS dev initialization Presently the HNS driver enables the HNS H/W error interrupts after the dev initialization is completed. However some exceptions such as NCSI errors can occur when the network port driver is not loaded and those errors required reporting to the BMC. Therefore the firmware enabled all the HNS ras error interrupts before the driver is loaded. And in some cases, there will be some H/W errors remained unclear before reboot. Thus the HNS driver needs to process and recover those hw errors occurred before HNS driver is initialized. This patch adds processing of the HNS hw errors(RAS and MSI-X) which occurred before the driver initialization. For RAS, because they are enabled by firmware, so we can detect specific bits, then log and clear them. But for MSI-X which can not be enabled before open vector0 irq, we can't detect the specific error bits, so we just write 1 to all interrupt source registers to clear.

The aRFS rules are also stored in the hardware flow director table, Use the existing filter management functions to insert TCPv4/UDPv4/TCPv6/UDPv6 flow director filters. To avoid rule conflict, once user adds flow director rules with ethtool, the aRFS will be disabled, and clear exist aRFS rules. Once all user configure rules were removed, aRFS can work again.

net: hns3: fix VLAN offload handle for VLAN inserted by port Currently, in TX direction, driver implements the TX VLAN offload by checking the VLAN header in skb, and filling it into TX descriptor. Usually it works well, but if enable inserting VLAN header based on port, it may conflict when out_tag field of TX descriptor is already used, and cause RAS error. In RX direction, hardware supports stripping max two VLAN headers. For vlan_tci in skb can only store one VLAN tag, when RX VLAN offload enabled, driver tells hardware to strip one VLAN header from RX packet; when RX VLAN offload disabled, driver tells hardware not to strip VLAN header from RX packet. Now if port based insert VLAN enabled, all RX packets will have the port based VLAN header. This header is useless for stack, driver needs to ask hardware to strip it. Unfortunately, hardware can't drop this VLAN header, and always fill it into RX descriptor, so driver has to identify and drop it.

net: hns3: add handling of hw errors reported through MSIX This patch adds handling for HNS3 hardware errors(non-standard) which are reported through MSIX interrupts and not through PCIe AER channel. These MSIX reported hardware errors are handled using common misc. interrupt handler. Hardware error related registers cannot be cleared in context to the interrupt received as they require *heavy* access to hardware using IMP(Integrated Mangement Processor) commands. Hence, we defer the clearing of such error events till later time. Since, we have defered exact identification of errors we will have to defer the level of receovery/reset which might be required. Hence, a new reset type UNKNOWN reset has been introduced which effectively defers the assertion of the reset till we get hold of kind of errors at later time.

net: hns3: implement the IMP reset processing for PF The current code only print the prompt message after receiving the IMP reset interrupt and does not perform the corresponding driver reset operation. This patch implements the missing IMP reset handling in the driver. 1. The driver sets the HCLGE_STATE_CMD_DISABLE to stop sending command after receiving the IMP reset interrupt. 2. The driver needs to notify the hardware to reload the IMP firmware. 3. The IMP firmware reloading makes the reset time of hardware longer, so it is necessary to extend the driver's waiting time to wait for the hardware reset to complete. 4. In hclge_check_event_cause, IMP reset event should have higher priority than other events. Also, after clearing HCLGE_STATE_CMD_DISABLE in the hclge_cmd_init(), it needs to check whether there is a pending reset, if so, just set the HCLGE_STATE_CMD_DISABLE back and return.

net: hns3: add reset handling for VF when doing PF reset When PF performs a function reset, the hardware will reset both PF and all the VF belong to this PF. Hence, both PF's driver and VF's driver need to perform corresponding reset operations. Before PF driver asserting function reset to hardware, it firstly set up VF's hardware reset status, and inform the VF driver with HNAE3_VF_PF_FUNC_RESET, then VF driver sets this reset type to reset_pending and shechule reset task to stop IO and waits for the hardware reset status to clear. When PF driver has reinitialized the hardware and is ready to process mailbox from VF, PF driver clears VF's hardware reset status for VF to continue its reset process. Also, this patch uses readl_poll_timeout to simplify the hardware reset status waitting.

net: hns3: add error handler for hclge_reset() When hclge_reset() is called, it may fail for several reasons. For example, an higher-level reset event occurs, memory allocation failure, hardware reset timeout, etc. Therefore, it is necessary to add corresponding error handling for these situations. 1. A high-level reset is required due to a high-level reset failure. 2. For memory allocation failure, a high-level reset is initiated by the timer to recover. The reason for using the timer is to prevent this new high-level reset to interrupt the reset process of other pf/vf; 3. For the case of hardware reset timeout, reschedule the reset task to wait for the hardware to complete the reset. For memory allocation failure and reset timeouts, in order to prevent an infinite number of scheduled reset tasks, the number of error recovery needs to be limited. This patch also add some reset related debug log printing. Signed-off-by: Huazhong Tan <tanhuazhong@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>

net: hns3: Enable promisc mode when mac vlan table is full Currently, the driver does nothing when mac vlan table is full. In this case, the packet with new mac address will be dropped by hardware. This patch adds check for the result of sync mac address, and enable promisc mode when mac vlan table is full. Furtherly, disable vlan filter when enable promisc by user command.

net: hns3: Fix for setting speed for phy failed problem The function of genphy_read_status is that reading phy information from HW and using these information to update SW variable. If user is using ethtool to setting the speed of phy and service task is calling by hclge_get_mac_phy_link, the result of speed setting is uncertain. Because ethtool cmd will modified phydev and hclge_get_mac_phy_link also will modified phydev. Because phy state machine will update phy link periodically, we can just use phydev->link to check the link status. This patch removes function call of genphy_read_status. To ensure accuracy, this patch adds a phy state check. If phy state is not PHY_RUNNING, we consider link is down. Because in some scenarios, phydev->link may be link up, but phy state is not PHY_RUNNING. This is just an intermediate state. In fact, the link is not ready yet.

net: hns3: Fix for the null pointer problem occurring when initializing ae_dev failed When initializing ae_dev failed during loading hclge.ko, the drvdata will be set to null. When removing hns3.ko, we get a null ae_dev. It causes the null pointer problem. This patch removes pci_set_drvdata from error handle of hclge_init_ae_dev to fix the bug, since pci_set_drvdata has been called in hns3_remove. Also, we do not need to uninit the ae_dev which is not initialized. And it may be the one which is initialized failed.

net: hns3: Fix for deadlock problem occurring when unregistering ae_algo When hnae3_unregister_ae_algo is called by PF, pci_disable_sriov is called. And then, hns3_remove is called by VF. We get deadlocked in this case. Since VF pci device is dependent on PF pci device, When PF pci device is removed, VF pci device must be removed. Also, To solve the deadlock problem, VF pci device should be removed before PF pci device is removed. This patch moves pci_enable/disable_sriov from hclge to hns3 to solve the deadlock problem. Also, we do not need to return EPROBE_DEFER in hnae3_register_ae_dev, because SRIOV is no longer enabled in the context calling hnae3_register_ae_dev. Mutex_trylock can be replaced with mutex_lock.

net: hns3: Refactors the requested reset & pending reset handling code In exisiting code, the way to detect if driver/client reset should be executed or if hardware should be be soft resetted was overly complex. Existing code use to read the interrupt status register from task context to figure out if the interrupt source event was reset and then use clear the interrupt source for reset while waiting for the hardware to finish the reset. This behaviour again was confusing and overly complex in terms of the flow. This patch simplifies the handling of the requested reset and the pending reset(i.e. reset which have already been asserted by the software and hardware has acknowledged back to driver that it is processing the hardware reset through interrupt) Signed-off-by: Salil Mehta <salil.mehta@huawei.com> Signed-off-by: lipeng <lipeng321@huawei.com> Signed-off-by: David S.

net: hns3: Add support for dynamically buffer reallocation Current buffer allocation can only happen at init, when doing buffer reallocation after init, care must be taken care of memory which priv_buf points to. This patch fixes it by using a dynamic allocated temporary memory. Because we only do buffer reallocation at init or when setting up the DCB parameter, and priv_buf is only used at buffer allocation process, so it is ok to use a dynamic allocated temporary memory.

net: hns3: Fix for setting rss_size incorrectly rss_size is 1, 2, 4, 8, 16, 32, 64, 128, but acutal tc queue size can be any u16 less than 128. If tc queue size is 5, we set the rss_size to 8, indirection table will be used to limit the size of actual queue size. It may cause dropping of receiving packet in hardware if rss_size is not set correctly. For now, each TC has the same rss size.

For ae_dev that doesn't support DCB, private rx buffer is assigned to zero, only shared rx buffer is used. So not setting the shared rx buffer cause dropping of packet in SSU.
